    ikev2: return v2_notification_t from ikev2_process_sa_payload()
    
    ... not STF_FAIL+v2N* or STF_FATAL.
    
    Return v2N_NO_PROPOSAL_CHOSEN when there's something suspect
    (missing DH say) about the proposal (not v2N_INVALID_SYNTAX).
    
    In callers use v2_notification_fatal() to determine if STF_FATAL
    should be returned to the state machine.
